Just purchased a nikon d40 with an 18-200 mm vr lens and there's a difference between the image on the camera's lcd screen and the image of the same picture on my computer using pictureproject. The image on the lcd is terrific - sharp and nice colors. However the same image in pictureproject is not sharp and slightly washed out colorwise. If I use the edit functions available on pictureproject then that image can be made to also look sharp & colorful. Why is there this difference to begin with?
